China’s Iran Ties Are Pragmatic, Unequal and Limited
China and Iran work together, especially on buying and selling oil.
China buys most of Iran’s exported oil, which helps Iran earn money despite sanctions.
However, Iran is much less important to China because it makes up less than 1% of China’s trade.
China also has invested far less in Iran than some large announcements suggested.
Chinese companies worry about being punished by United States sanctions.
China has not publicly promised to protect Iran militarily.
Reports about Chinese weapons or military supplies to Iran have mostly not been confirmed.
Instead, China tries to keep good relationships with Iran and with Iran’s rivals.
This means the partnership is useful but not as close or strategic as it may appear.
China buys about 90% of Iran’s oil exports but Iran represents less than 1% of China’s commerce.
Beijing’s confirmed investment in Iran is estimated at $2 billion to $3 billion, far below the $400 billion headline figure.
China’s economic relationship with Iran is much smaller than its partnerships with Saudi Arabia and the United Arab Emirates.
Chinese military support for Iran remains limited, with alleged weapons or dual-use transfers largely unconfirmed.
Beijing continues diplomatic engagement with Tehran while balancing relations with the United States, Russia, Saudi Arabia and the United Arab Emirates.

Strategic alignment

Military support
